Structural and magnetic phase transitions in mineralsThis volume in Advances in Physical Geochemistry presents the latest synthesis of theory and experimental data pertaining to structural and magnetic phase transitions in a variety of geochemically important minerals. The book is the first to cover the impact of this rapidly progressing area of solid state physics in earth sciences and reflects its growing significance for mineralogy and petrology. |

Newer experimental data for the Di-En and multicomponent systems obviate the
need for this approach. The Wood-Banno paper and Boyd's (1973) study, which
showed the potential value of pyroxene assemblages for recording fossil ...

Calorimetric experiments (Chatillon-Colinet et al., 1983) on orthopyroxenes
synthesized at 1 120°C, 20 kbar, with compositions En100-FsIOo, also show
positive departure from ideality. Excluding standard-state contributions, solution

In our experiments, we found that only the transformation between phases 2H
and 12R could be reversed in a relatively short time, and we focused exclusively
on the experimental investigation of this phase transition. We hope that the
